Went into my local dealer in Aus last week, there was a sign saying "MS462 Coming Soon"
Went back today, found this where the sign used to be.
I had a good look at the MS462 and the MS661 on the rack next to it, they are EXTREMELY similarly constructed. From what i could see from the outside, the MS462 is pretty much a slightly shrunken MS661.
Same shape, same style, almost identical AV setup.
Quite a bit lighter than the MS661 though. Looks like the ones in Aus are M-tronic V3.
For a price reference, the MS462 was advertised at AU$1899, the MS661 next to it was AU$2099, so exactly AU$200 between the MS642 and MS661.
Just looking on the STIHL Australia website, they have the MS462 advertised for AU$1959 (AU$60 more than in store).
EDIT: Apparently the MS462 is AU$1899 with the standard bar and AU$1959 with the ES Light bar.
